CenturionIn the Roman army during classical antiquity, a centurion (sɛnˈtjʊəriən; centurio kɛn̪ˈt̪ʊrioː, (). centuriones; kentyríōn, or hekatóntarkhos), was a commander, nominally of a century (centuria), a military unit originally consisting of 100 legionaries. The size of the century changed over time, and from the first century BC through most of the imperial era was reduced to 80 men. In a Roman legion, centuries were grouped into cohorts and commanded by their senior-most centurion.
Praetorian GuardThe Praetorian Guard (Latin: cohortēs praetōriae) was an elite unit of the Imperial Roman army that served as personal bodyguards and intelligence agents for the Roman emperors. During the Roman Republic, the Praetorian Guards were escorts for high-ranking political officials (senators and procurators) and were bodyguards for the senior officers of the Roman legions. In 27 BC, after Rome's transition from republic to empire, the first emperor of Rome, Augustus, designated the Praetorians as his personal security escort.
ThraciaThracia or Thrace (Θρᾴκη Thrakē) is the ancient name given to the southeastern Balkan region, the land inhabited by the Thracians. Thrace was ruled by the Odrysian kingdom during the Classical and Hellenistic eras, and briefly by the Greek Diadochi ruler Lysimachus, but became a client state of the late Roman Republic and early Roman Empire as the Sapaean kingdom. Roman emperor Claudius annexed the kingdom as a Roman province in 46 AD.
Roman infantry tacticsRoman infantry tactics are the theoretical and historical deployment, formation, and manoeuvres of the Roman infantry from the start of the Roman Republic to the fall of the Western Roman Empire. The focus below is primarily on Roman tactics: the "how" of their approach to battle, and how it stacked up against a variety of opponents over time. It does not attempt detailed coverage of things like army structure or equipment. Various battles are summarized to illustrate Roman methods with links to detailed articles on individual encounters.
Crisis of the Third CenturyThe Crisis of the Third Century, also known as the Military Anarchy or the Imperial Crisis (235–284), was a period in which the Roman Empire nearly collapsed. The crisis ended due to the military victories of Aurelian and with the ascension of Diocletian and his implementation of reforms in 284. The crisis began in 235 with the assassination of Emperor Severus Alexander by his own troops. During the following 50-year period, the Empire saw the combined pressures of barbarian invasions and migrations into Roman territory, civil wars, peasant rebellions and political instability, with multiple usurpers competing for power.
Commentarii de Bello GallicoCommentarii de Bello Gallico (kɔm.mɛnˈtaː.ɾi.iː deː ˈbɛl.loː ˈɡal.lɪ.koː; Commentaries on the Gallic War), also Bellum Gallicum (Gallic War), is Julius Caesar's firsthand account of the Gallic Wars, written as a third-person narrative. In it Caesar describes the battles and intrigues that took place in the nine years he spent fighting the Celtic and Germanic peoples in Gaul that opposed Roman conquest. The "Gaul" that Caesar refers to is ambiguous, as the term had various connotations in Roman writing and discourse during Caesar's time.
GaleriusGalerius Valerius Maximianus (ɡəˈlɛəriəs; Greek: Γαλέριος; 258 – May 311) was Roman emperor from 305 to 311. During his reign he campaigned, aided by Diocletian, against the Sasanian Empire, sacking their capital Ctesiphon in 299. He also campaigned across the Danube against the Carpi, defeating them in 297 and 300. Although he was a staunch opponent of Christianity, Galerius ended the Diocletianic Persecution when he issued an Edict of Toleration in Serdica in 311.
TrajanTrajan (ˈtreɪdʒən ; Caesar Nerva Traianus; 18 September 53 11 August 117) was Roman emperor from 98 to 117. Trajan was born and raised in Italica, close to modern Seville in present-day Spain, a small Roman municipium of Hispania Baetica founded by Scipio as an Italic settlement; his branch of the Ulpia gens, the Ulpii Traiani, came from the town of Tuder in the Umbria region of Italia. Trajan's father, Marcus Ulpius Traianus, also from Italica, was a senator. Trajan rose to prominence during the reign of Domitian.
Pyrrhic WarThe Pyrrhic War (280–275 BC) was largely fought between the Roman Republic and Pyrrhus, the king of Epirus, who had been asked by the people of the Greek city of Tarentum in southern Italy to help them in their war against the Romans. A skilled commander, with a strong army supported by war elephants (which the Romans were not experienced in facing), Pyrrhus enjoyed initial success against the Roman legions, but suffered heavy losses even in these victories.
Trajan's BridgeTrajan's Bridge (Podul lui Traian; Трајанов мост), also called Bridge of Apollodorus over the Danube, was a Roman segmental arch bridge, the first bridge to be built over the lower Danube and one of the greatest achievements in Roman architecture. Though it was only functional for 165 years, it is often considered to have been the longest arch bridge in both total and span length for more than 1,000 years. The bridge was constructed in 105 AD by instruction of Emperor Trajan by architect Apollodorus of Damascus, from Damascus, Roman Syria, before his Second Dacian War to allow Roman troops to cross the river.
